Closed source projects might want to set up Bugzilla with access to the public so they can read bugs and query on them. However, there might be times when attachments are needed with source. It would be really great to restrict access to certain attachments so the public can read the bug still and track it's progress, but unable to view the closed source proprietary code.
This would be very useful for us here at Red Hat also.
